New computer (Windows 11) shows 'Old Firefox Data'. Opened hidden files. Using File Explorer found Profile Folder & renamed it 'old'. Copied and pasted 'Old Firefox Data' as new profile. Firefox would not open. Had to remove etc and Firefox worked again. Thought this maybe the easiest way to get my Bookmarks back.

PS Presume Profile Folder does not contain Thunderbird Addresses?

A tab for the Etsy website automatically appears every time FF starts up. How to stop this?

Just began after using the site a couple of times, but I did not indicate or click a setting on the Etsy site to ask for this.

All solution suggestions seem to be for pop-up ads, and don't work to block a website. Is there a way to block this?

I decided to migrate from chrome to firefox, sadly, my experience has been faced with random slow downs or partial loads even on a fresh install. It's weird but it seems that at random times some websites will refuse to fully load or even start loading, it appears that the app is just hanging. This is usually fixed after several refreshes. Oddly enough, even on a fresh install, if I attempt to load up the same website while in private browsing, it loads right away, again this is consistent even on a fresh install, the attached image was an attempt to load youtube after signing in on a fresh install without add-ons, I tried loading up youtube in private and it worked right away. Chrome wasn't presenting this problem on my computer for years. Any ideas? My computer specs are high enough where they shouldn't matter. I'm running an AMD GPU (7900 XTX) but I haven't found any know issues regarding these, to even discard that, I disabled hardware acceleration, but the issue persisted. Running up to date windows 10, installing latest version of firefox.

when i have any of those 2 flags set to true it opens all links i middle click from firefox-view history all the way to left since firefox-view isn't a tab. I'd rather have it force them all to the right by default instead of it thinking i am not in a tab and have no tabs open

Is there literally no way to control firefox's memory usage? I have tried a lot of things and none of them work

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

Hello,

I have tried many times to import my passwords from Chrome and from my desktop Firefox, using synchronising, to this laptop, and it has continually failed to happen. My Tabs and Bookmarks, for example, have all been successfully imported.

I want to make Firefox my default browser but cannot do this without successfully importing my passwords.

Please let me know what I should do next.

Are you able to take control of my laptop remotely and resolve the problem? If so, please let me know the times and days when you can do this, so that I can make an appointment, stating which time zone you are in as I am in England.

Many thanks, Michael

I have search separated from the url bar, and I have Firefox Suggest configured to only use history for tab completion. I've noticed a couple problems.

  • Search is being prioritized over options in my history. I have the separate search box, if I wanted to search I would use it. If I type a single character I want the most common result from my history to be the result of hitting tab.
  • I've noticed recently that I'm getting sponsored results even though I have them disabled. It's somewhat inconsistent, and I've only noticed it in one of my profiles. Specifically I am used to "w <tab>" taking me to weather.gov but I'm getting sponsored results for AccuWeather. I clicked the "feedback -> not interested" button but this is concerning that Firefox is ignoring preferences and there's a pattern of sending data to Google and AccuWeather despite me configuring the browser not to.

Had to reinstall my pc over consistent error messages (thank you windows 10 for being the same pos system), and now all my bookmarks are gone, the bookmark backup folder is also empty, I have two years worth of personal and business related sites saved that will cripple me financially and mentally if I can't get them back.

Reaching out to Sync to try that, but looking for any kind of alternative fix here to recover the bookmarks.
